Background and Aim: In hemodialysis patients, 24-hours interdialytic ABPM better detects TOD than dialysis unit blood pressure. Therefore, the present study was aimed to assess the diagnostic performance of 24-hours ABPM vs. dialysis unit BPs for the diagnosis of ECG-LVH in steady state chronic hemodialysis black patients. Methods: From March 31 to September 30, 2018, interdialytic ABPM was performed after a mid-week hemodialysis session for 24 hours using a Spacelab 90207 ABPM monitor in the non-access arm in 45 stable chronic hemodialysis black patients (age ≥ 20 years, hemodialysis for at least 3 months and informed consent) attending 3 hemodialysis centers in Kinshasa. Ambulatory BP was recorded every 20 minutes during the day (6 AM to 10 PM) and every 30 minutes during the night (10 PM to 6 AM). ECG-LVH was defined using Cornell product criteria. ROC curve method was used to assess the performance of dialysis unit BPs vs. interdialytic 24-hours ABPM in diagnosing ECG-LVH. P < 0.05 defined the level of statistical significance. Results: Whatever the method of BP measurement, all the SBP values were related to ECG-LVH with similar AUC and overlapping 95% CI; however, they were not significantly different from each other. 24-hours interdialytic ambulatory SBP (AUC 0.748; 95% CI 0.58 - 0.94) had the highest area under the curve. Conclusion: The present study showed that although all the two BP measurement methods equally detected ECG-LVH, 24-hours ABPM tended to have the highest diagnostic performance.
